I’ve had conversations with dozens of homeowners, installers and energy traders about this exact question: can a Tesla Powerwall owner in the UK legally export stored power back to the grid and actually earn money from it? The short answer is yes — but with important caveats. In this piece I’ll walk you through the rules, the practicalities, the pitfalls and the best ways to monetise...
Retrofitting a 1930s semi for heat pumps and airtightness is one of those projects that feels equal parts exciting and...

I’ve worked with landlords, tenants and energy professionals long enough to know that pushing for energy-efficient retrofits isn’t just good for the planet — it makes financial and reputational sense. Whether you own a single buy-to-let or manage a small portfolio, knowing which clauses to...

I often get asked whether an achat de véhicule utilitaire par une SCI is a sensible move. The question sits at the intersection of company law, tax strategy, and practical fleet management — and it's particularly relevant for property-owning structures like a Société Civile Immobilière (SCI)...

When I first started exploring the potential of second-life EV batteries for community energy projects, I imagined quiet streets powered during peak hours by batteries that once propelled electric cars. That vision turned into a practical project idea: a street-level microgrid combining rooftop...

I often get asked by festival organisers and event operators how to provide rapid EV charging on-site without relying on grid upgrades. Over the past few years I've helped design several pop-up charging hubs powered primarily by local solar and battery storage. In this article I walk you through...

I get asked a lot whether a Nissan Leaf or a Tesla can reliably power a home for a week. It's a tempting idea: your car doubles as a giant battery, keeping lights on, refrigerators running, and maybe even a small heater humming while the grid is down — or allowing you to go off-grid for a short...

I recently helped a neighbour replace an ageing gas boiler with an air-source heat pump. Watching the first winter bills come through, and sitting through the commissioning day with the installer, I realised how many hidden costs and mistakes can turn what should be a smart, efficient upgrade into...

I’ve spent a lot of time thinking about how home batteries fit into real people’s lives — not just as shiny gadgets, but as practical tools during extreme events like consecutive winter blackouts. If you’re asking, "Can a Tesla Powerwall save me money during long, repeated winter outages?"...

I’ve been watching the rise of community solar paired with shared batteries for several years now, and I’m convinced this combination could be a powerful lever for local councils trying to cut their energy bills while delivering social and environmental benefits. But the question I get asked...

I get asked a lot: "Will perovskite solar roofs survive UK weather, and what real performance can I expect?" It's a fair question. After years covering renewables and talking to researchers, installers and early-adopter homeowners, I’ve formed a practical view that balances excitement with...

I started thinking about the real climate impact of everyday kitchen choices after we replaced our old gas hob with an induction one and upgraded our extraction system. Friends asked whether the swap was just about convenience and cleaner indoor air — or if it actually made a measurable dent in...
